Price range: $119.99 through $139.99

The 322A and 322B represent a new class of high-efficiency two-in-one thermal imaging multimeter devices, combining a 240×240 super-resolution thermal camera with a 60,000-count True-RMS digital multimeter. Unlike conventional thermal testers that offer only basic temperature readings, the 322 series delivers professional electrical measurement capabilities—DC/AC voltage up to 1000V/750V, current up to 10A, resistance, capacitance, frequency, diode test, and continuity beeper. The thermal side includes 7 false color palettes, center/max/min temperature tracking, a 25Hz refresh rate, and optional macro lens for 1mm component inspection. The 322B model further adds a 10mW red light function (1Hz/2Hz/off) and an optical power meter (dBm, mW, μW), making it ideal for fiber optics and low-power laser systems. With 60-group data storage, a bright 3.2-inch color screen, and clear icons for battery charging and data storage status, this device is built for field engineers, lab technicians, and energy auditors. Whether you are hunting for a short circuit via thermal rise or verifying a 600.00mV sensor signal, the 322A/322B is the two-in-one thermal imaging multimeter that eliminates tool clutter and accelerates fault finding.

  • Revolutionary Two-in-One Synergy: Thermal Imaging + Multimeter in One Device
    The 322A and 322B are not just thermal cameras; they are fully featured, high-accuracy digital multimeters. This two-in-one design eliminates the need to carry separate tools, allowing you to visualize heat patterns and measure electrical parameters simultaneously. Whether you are troubleshooting a PCB, a solar array, or an industrial control panel, the high-efficiency thermal imaging multimeter gives you both data and thermal context in real time.
  • Upscaled 240x240 Super-Resolution Thermal Imaging
    Unlike entry-level thermal imagers with fuzzy images, the 322 series delivers upscaled 240x240 thermal imaging resolution. This clarity allows you to identify overheated components, loose connections, and insulation failures from 0.2 to 3 meters. With a spatial resolution of 8.8 mrad and a 25Hz frame rate, the device provides smooth, real-time video-grade thermal feedback. The macro lens option lets you clearly see components as small as 1mm, making it perfect for SMD board inspection.
  • Professional 60,000-Count True-RMS Multimeter
    Most combination tools compromise on multimeter accuracy. The 322 series does not. It features a 60,000-word display—far superior to the common 6,000-count meters. True-RMS (Root Mean Square) ensures precise AC voltage and current measurements even with non-sinusoidal waveforms. Key ranges include:
    • Direct Voltage: 600.00mV to 1000V ±(0.5%+0.3)
    • Alternating Voltage: 600.00mV to 750V ±(0.8%+0.5)
    • Direct/Alternating Current: up to 10A
    • Resistance up to 60MΩ, Capacitance up to 60mF, Frequency up to 6MHz
      This two-in-one thermal imaging multimeter replaces your bulky tool bag with one rugged solution.
  • 7 Types of False Color & 3.2-Inch Color Screen
    Thermal data is only useful if it is intuitive. The 3.2-inch dot matrix color screen (240x320) offers vivid clarity, while 7 types of false color palettes help you quickly differentiate temperature gradients. From ironbow to rainbow high-contrast, choose the palette that highlights faults best. The 91.8°C maximum measurable temperature (center point tracking) and 2°C or 2% precision ensure industrial-grade reliability.
  • Exclusive 322B Features: Red Light Function & Optical Power Meter
    The 322B model adds two game-changing capabilities. First, the red light function (10mW) with selectable 1Hz/2Hz flashing or continuous mode—ideal for fiber optic identification or visual signaling in dark server rooms. Second, the optical power meter measures in mW, μW, and dBm (-70.00 to 6.00 dBm). This transforms the high-efficiency two-in-one thermal imaging multimeter into a fiber optic technician’s best friend, combining thermal inspection with optical power validation.
  • Comprehensive Temperature Measurement Rules & Data Storage
    The thermal imager is not just for looking—it is for analyzing. Three temperature measurement rules are included: center pointmaximum temperature (tracking the hottest spot automatically), and minimum temperature (finding cold leaks or missing phases). You can store up to 60 groups of thermal images on the device. Additional icons on the display indicate battery chargingdata storage status, and TPR protection (Transient Protection Rating), ensuring safety during high-energy electrical tests.
  • Built for Field Use: Durability, Safety, and Ease of Use
    With 10A/300V fuse specifications, diode test, and continuity beeping (<10Ω), this tool meets safety requirements for CAT II/III environments. The HOLD function freezes both thermal and multimeter readings. The static OK/SET button interface makes menu navigation intuitive. Battery charging is via USB-C (implied from icon), so you can recharge from a power bank or laptop. The test distance of 0.2-3 meters (0.1m x 0.1m minimum target) means you can safely inspect live panels from a distance while the multimeter probes handle the fine work.
  • From PCB Repair to HVAC: A Cross-Industry Workhorse
    Electrical engineers, HVAC technicians, automotive electricians, and renewable energy installers will benefit from this device. Find a hot MOSFET on a controller board (using macro lens), measure its exact DC voltage with the 60,000-count multimeter, then switch to frequency mode to check PWM signals. For photovoltaic systems, use thermal imaging to locate a bypass diode failure while measuring string voltage and current. The two-in-one thermal imaging multimeter closes the gap between visual heat signatures and quantitative electrical data.
  • Clutter-Free Workflow: All Data, One Screen
    The interface splits into two logical areas: left side for thermal settings (palette, unit, emissivity, temperature compensation) and right side for multimeter results (optical power nW, dB, dBm). Parameters like emissivity preset and automatic temperature compensation ensure accurate non-contact temperature readings on various surfaces (metal, plastic, painted wood). This design reduces menu diving and speeds up daily routines.
  • High Value, Low Total Cost of Ownership
    Buying a standalone 240x240 thermal imager and a 60,000-count True-RMS multimeter would cost several times more. The 322A/322B offers both in a rugged, portable housing. The 322B, with its red light and optical power meter, replaces three devices. No recurring calibration fees for typical field use, and the 25Hz frame rate provides smooth, non-frustrating scanning. This is the high-efficiency two-in-one thermal imaging multimeter for engineers who demand professional results without the prosumer price tag.
